Stop copy-pasting config files from old projects
Every new repository starts with the same chores: write a .gitignore so build artifacts and secrets stay out of Git, write a Dockerfile so the app builds into a clean container, and — if you're on Apache — write an .htaccess for HTTPS, redirects, compression and caching. Getting each one right from memory is error-prone. These three free generators do it for you, correctly, in seconds, and entirely in your browser.
1. The .gitignore generator
Select any combination of languages (Node, Python, Go, Rust, Java, PHP and more), frameworks (React, Next.js, Django, Laravel, Flutter…), editors (VS Code, JetBrains, Vim) and operating systems. The .gitignore generator merges the matching official GitHub templates into one file, removes duplicate rules, and labels each section — ready to drop into your repo root.
2. The Dockerfile generator
Pick your runtime and version, set the port, and the Dockerfile generator writes an optimized, multi-stage Dockerfile: a builder stage compiles your app and a minimal final stage ships only the artifact, with smart layer caching and a non-root user baked in. A matching .dockerignore is included.
3. The .htaccess generator
Toggle the rules you need and the .htaccess generator produces a clean, commented Apache config: force HTTPS, redirect www/non-www, enable gzip and browser caching, add security headers, block hotlinking, and set custom error pages. Built live, with your domain filled in.
Why client-side?
Because config files often reference internal details — your domain, your stack, your structure — none of that should be sent to a third-party server just to generate a text file. All three tools run 100% in your browser using bundled data and JavaScript. There's no signup, no tracking of your inputs, and they keep working even offline once the page has loaded. They're hosted on Cloudflare's global edge for instant load anywhere.
